import axios from 'axios'
//1.实例化axios对象
var service = axios.create({
    timeout: 10*100,

//2.设置请求拦截器
service.interceptors.request.use(

        return config

//3.设置响应拦截器

        if (error.response.status == 401) {

            alert('服务器内部错误!')
        }
        return Promise.reject(error)
    }

// 4.导出service
export default service
